Waste Water Plumbing in Cyclone 4250

I have a 2018 Cyclone 4250. It has 1-1/2 bathrooms and 2 separate sets of black and grey water tanks and tank valves. The first time we went to dump the tanks we started with the forward set, hooked the hose up and dumped both tanks with no issues. I pull forward 15 feet hook the hose to the rear tanks and open the black tank valve. When it was empty I opened the grey water valve and lo and behold it dumps out 20 gals from the front tank connection all over the ground. So it looks like both grey water tanks and the forward black water tank dump from the front connection and only the rear black water tank dumps from the rear connection. Does this seem right or does anyone think I have some kind of plumbing issue?

No issue, that's the way ours is. I always dump the rear black tank first then the front then the gray tanks.
